Troubleshooting
2-5
Table 2-1
Continued
Hard disk controller error
The hard drive controller
failed to respond to the
reset command.
Check the drive parameters. Turn
off the system and check all
related connections.
Keyboard controller failure
The keyboard failed the
self-test command.
Replace the system board.
Keyboard failure
The keyboard failed to
respond to the RESET ID
command.
Replace the keyboard. If the
problem persists, replace the
system board.
No interrupts from Timer 0
The periodic timer interrupt
is not occurring.
Replace the system board.
ROM at xxxx (LENGTH yyyy)
with nonzero checksum (zz)
An illegal adapter ROM
was located at the
specified address.
Check the external adapter (such
as a video card) to determine if
it is causing the conflict.
Time/Date corrupt - run SCU
The time and date stored
in the real time clock have
been corrupted, possibly
by a power loss.
1. Run Computer Setup.
2. If problem persists, replace
auxiliary battery.
3. If problems persists, replace
system board.
Hard disk xx failure (or error)
A failure or an error
occurred when trying to
access the hard drive.
1. Run ScanDisk.
2. Check disk in DOS and
Windows 95.
Fatal errors emit a beep and may display a FATAL message. Fatal errors indicate
severe problems, such as a hardware failure. Fatal errors do not allow the system to
resume. Some of the Fatal error beep codes are listed at the end of this section.

Fatal Error Messages
Message
Description
Beep code
CMOS RAM test failed
A walking bit test of CMOS RAM location
0E (Hex) - 3F (Hex) failed.
3
DMA controller faulty
A sequential read/write of the transfer
count and transfer address registers
within the primary and secondary DMA
controllers failed.
4
Faulty DMA page registers
A walking bit read/write of the 16 DMA
controller page registers starting at
location 80 Hex failed.
0
Faulty refresh circuits
A continuous read/write test of port 61h
found that bit 4 (Refresh Detect) failed
to toggle within an allotted amount of
time.
1
Interrupt controller failed
A sequential read/write of various
Interrupt Controller registers failed.
5
ROM checksum incorrect
A checksum of the ROM BIOS does not
match the byte value at F000:FFFF.
2
RAM error at location xxxx
RAM error occurred during memory test.
None
